[0050] Example 1

[0051] Please refer to Figure 1This embodiment provides a vent valve, including: a housing 311 and a pull rod 312; a vent hole 314 is provided at the first end of the housing 311; a vent hole 315 is provided in the housing 311; the first end of the pull rod 312 is inserted into the housing 311 and connected to a sealing gasket 313, and the second end extends out of the housing 311; the pull rod 312 pushes the sealing gasket 313 to seal the vent hole 314. The sealing gasket 313 is preferably made of silicone. When the vent valve is in operation, the pull rod 312 pulls the sealing gasket 313 to open the vent hole 314 to connect with the vent hole 315 for venting.

[0052] In one embodiment, the pull rod 312 includes a rod head 3122 and a rod body 3121; the rod head 3122 is disposed within a housing 311; the rod head 3122 is cylindrical; and the rod body 3121 is disposed on the first end face of the rod head 3122. The rod body 3121 preferably has a slender structure, with dimensions smaller than the rod head 3122. The housing 311 has a clearance hole at its second end, through which the rod body 3121 extends. Specifically, the center of the housing 311 forms an interface 317 by inwardly flanging, and the clearance hole is located within the interface 317; the rod body 3121 passes through the interface 317, and the inner wall of the interface 317 guides the linear pushing and pulling motion of the rod body 3121.

[0053] In one embodiment, an annular mounting groove is formed on the cylindrical surface of the rod head 3122; the sealing gasket 313 covers the second end face of the rod head 3122, and the edge of the sealing gasket 313 is engaged with the mounting groove.

[0054] In one embodiment, the housing 311 is provided with an elastic element connecting the pull rod 312. The elastic element provides a preload force, which acts on the sealing gasket 313 to engage the vent hole 314 and achieve a sealing effect. The elastic element can be a spring 316, an elastic column, an elastic strip, or an elastic band, etc. Regarding the design of the spring 316: the pull rod 312 is fitted with a spring 316, which is located inside the housing 311. The first end of the spring 316 abuts against the inner wall of the second end of the housing 311, and the second end of the spring 316 abuts against the end face of the first end of the rod head 3122. The spring 316 provides a preload force to push the sealing gasket 313 to seal the vent hole 314. After the pull rod 312 pulls the sealing gasket 313 to open the vent hole 314 and releases air, the compressed preload force of the spring 316 pushes the sealing gasket 313 to seal the vent hole 314. Regarding the design of the elastic column: First, the center of the elastic column is hollow, and the elastic column is similar to a spring 316 sleeved outside the pull rod 312; Second, the first end of the elastic column abuts against the inner wall of the second end of the housing 311, and the second end of the elastic column abuts against the end face of the first end of the rod head 3122; The elastic column provides the pre-tightening force to push the sealing gasket 313 to seal the vent hole 314. After the pull rod 312 pulls the sealing gasket 313 to open the vent hole 314 to release air, the pre-tightening force of the elastic column pushes the sealing gasket 313 to seal the vent hole 314. Regarding the design of the elastic strip or elastic band: The first end of the elastic strip / elastic band is connected to the inner wall of the first end of the housing 311 (note to avoid the mating surface between the vent 314, the sealing gasket 313 and the first end of the housing 311, so as not to affect the sealing effect), and the second end of the elastic strip / elastic band is connected to the second end of the rod head 3122 (note to avoid the second end face of the rod head covered by the sealing gasket 313, so as not to affect the sealing effect); the elastic strip / elastic band is stretched to provide a pre-tightening force to pull the sealing gasket 313 to engage the vent 314 and form a seal. After the pull rod 312 overcomes the pre-tightening force of the elastic strip / elastic band and continues to pull the sealing gasket 313 to open the vent 314 to release air, the pull rod 312 pushes back, and the pre-tightening force of the elastic strip / elastic band pulls the sealing gasket 313 again to seal the vent 314.

[0055] In one embodiment, the housing 311 includes a first housing body 3111 and a second housing body 3112. The second housing body 3112 is detachably connected to the first housing body 3111, such as by snap-fit ​​or threaded connection. A clearance hole and an interface 317 are provided on the first housing body 3111, and a vent 314 is provided on the second housing body 3112. Preferably, the second housing body 3112 is provided with a connecting pipe 318 communicating with the vent 314, and the connecting pipe 318 extends outward from the second housing body 3112 for connecting an external air pipe 32.

[0056] In one embodiment, the vent hole 315 is disposed on the side of the housing 311, and the vent hole 315 is preferably formed on the second housing body 3112; a venting channel is formed between the side of the sealing gasket 313 and the inner wall of the housing 311, and the venting channel is used for gas to flow into the vent hole 315 for venting when the vent hole 314 is opened. Preferably, multiple vent holes 315 are provided, and the multiple vent holes 315 are evenly arranged around the housing 311. In this case, to ensure that the venting channel can communicate with the multiple vent holes 315, the venting channel is annular; in other words, the housing 311 can be cylindrical, and the first end of the pull rod 312 is a cylindrical rod head 3122, the outer diameter of which is smaller than the inner diameter of the housing 311, so that a gap is formed between the inner wall of the housing 311 and the sealing gasket 313 installed on the rod head 3122, and this gap is the annular venting channel. As long as the lever 312 pulls the sealing gasket 313 to slightly open part of the vent 314, the gas can flow through the vent channel to the vent 315 to release the gas.

[0057] In one embodiment, the vent 315 is disposed on the side of the housing 311, and the vent 315 is preferably formed on the second housing body 3112. The outer circular surface of the sealing gasket 313 is in close contact with the inner wall of the second housing body 3112. The pull rod 312 pulls the sealing gasket 313 to open the vent 314, and continues to pull the sealing gasket 313 to make the sealing surface of the sealing gasket 313 (i.e., Figure 1 The lower end face of the sealing gasket 313 opens the vent hole 315 (part of it). At this time, the vent hole 315 is connected to the vent hole 314, and the vent hole 315 vents air outward.

[0058] In one embodiment, the vent 315 is located at the first end of the housing 311, and the vent 315 is preferably located on the bottom surface of the second housing body 3112. When the pull rod 312 pulls the sealing gasket 313 away from the vent 314, the vent 314 and the vent 315 can be opened simultaneously and connected, so that the vent 315 can naturally release air outward.

[0059] Example 2

[0060] Please refer to Figures 1-3 This embodiment provides an adsorption device, including: a vent valve 31 as described in Embodiment 1 above; wherein, the vent 314 of the vent valve 31 is connected to a suction cup 33 through an air pipe 32.

[0061] In one embodiment, multiple suction cups 33 can be provided. The combination of multiple suction cups 33 makes the adsorption more stable and effectively prevents air leakage from the suction cups 33. The number of suction cups 33 is preferably four arranged in an array. The four suction cups 33 are connected to the vent 314 of the connecting pipe 318 through a four-way connector. The suction cups 33 can be rigid suction cups or soft suction cups. When multiple suction cups 33 are used, the adsorption of each suction cup 33 can be controlled simultaneously or individually through the vent valve 31 connected by the pipe; when one suction cup 33 leaks air, it will not affect the venting of other suction cups 33, which improves safety and makes it applicable to more scenarios.

[0062] Example 3

[0063] Please refer to Figures 1-7 This embodiment provides a base station that can house, charge, manage, and control window cleaning robots, and also provides security protection for the base station. The base station includes: a base station body 1 and an adsorption device 3 as described in Embodiment 2 above; the vent valve 31 is located inside the base station body 1; the suction cup 33 is located at the bottom of the base station body 1 and is used to adhere to the surface of an object to fix the base station body 1.

[0064] In one embodiment, the base station body 1 is provided with a handle 2, the end of which is rotatably engaged with the base station body 1; the handle 2 is connected to an actuator 5, which is used to drive the pull rod 312 to drive the sealing gasket 313 to open the vent 314 when the handle 2 rotates. To facilitate manual operation of the base station, the handle 2 is preferably located on the top of the base station body 1; more preferably, the base station body 1 is provided with a storage groove that matches the handle 2, the storage groove being used to accommodate the handle 2 in the lowered state.

[0065] In one embodiment, the handle 2 is U-shaped, and an actuator 5 is provided at one end of the handle 2, so that when the handle 2 is lifted, the end of the handle 2 is rotated and the pull rod 312 drives the sealing gasket 313 to open the vent 314.

[0066] In one embodiment, the actuator 5 includes: a connecting element 51 and an actuator 52; the connecting element 51 is located at the end of the handle 2; the connecting element 51 has a lug; the actuator 52 is vertically connected to the plate surface of the lug; the actuator 52 is used to engage the connecting rod 4 at the second end of the pull rod 312 when the handle 2 rotates, thereby pulling the pull rod 312 to drive the sealing gasket 313 to open the vent 314, and the connecting rod 4 is used to drive the pull rod 312. The actuator 52 is preferably a protruding post. Preferably, the end of the connecting rod 4 has a notch; of course, the actuator 52 can also directly engage the pull rod 312 to pull the pull rod 312, in which case the second end of the pull rod 312 has a notch; when the handle 2 rotates, the actuator 52 engages the notch and pulls the pull rod 312 outward to open the vent 314. The notch is relatively large. When the actuator 52 engages with the notch, the actuator 52 can move relative to the notch, preventing the actuator 52 from rotating and causing the pull rod 312 to move non-linearly, thus preventing damage to the vent valve 31 or the base station body 1. It is understood that the notch can also be replaced by an opening, which is clearance-fitted with the actuator 52.

[0067] In one embodiment, during the lifting process, the handle 2 only triggers the air release function after being lifted to a certain angle (approaching the lifted state of the handle 2), ensuring that the suction cup 33 maintains its adsorption function even when the handle 2 is not manually lifted, thus avoiding the safety risk caused by the suction cup 33 losing its adsorption function when the handle 2 is in a semi-reset angle. This effect is achieved by creating a notch at the second end of the pull rod 312 or the end of the connecting rod 4. Specifically, the notch penetrates through the first side of the pull rod 312 or the connecting rod 4 and faces the actuator 52. When the actuator 52 rotates with the handle 2, it enters the notch to engage the pull rod 312 or the connecting rod 4. Preferably, the notch has an arc edge that matches the rotation trajectory of the actuator 52. As the handle 2 rotates, the actuator 52 moves along the arc edge. During this movement, the actuator 52 does not engage the pull rod 312 or the connecting rod 4, and therefore cannot trigger the pull rod 312 to pull the sealing gasket 313 to release air. Only after the actuator 52 has fully moved into the deepest part of the notch does it engage the pull rod 312 or the connecting rod 4. As the actuator 52 continues to rotate, it triggers the pull rod 312 to pull the sealing gasket 313 to release air. Therefore, the process of the actuator 52 moving along the arc edge to the deepest part of the notch corresponds to the angle at which the air release function is triggered as mentioned above.

[0068] In one embodiment, the second end of the pull rod 312 or the end of the connecting rod 4 extends out of the base station body 1, so that the actuator 52 can engage the pull rod 312 or the connecting rod 4 to pull the extension when the handle 2 rotates.

[0069] In the base station of this utility model, when the handle 2 is lifted, the protrusion linked to the handle 2 rotates and activates the pull rod 312, pulling the pull rod 312 to open the vent valve 31. The suction cup 33 releases air through the vent hole 315, and the suction cup 33 loses its adsorption function. When the handle 2 is lowered, the vent valve 31 closes, and the suction cup 33 regains its adsorption function. The adsorption process of the suction cup 33 is as follows: the weight of the base station body 1 compresses the suction cup 33, expelling the air from the suction cup 33, creating a vacuum negative pressure inside the suction cup 33, allowing the suction cup 33 to be fixed to the surface of the object; when the vent valve 31 is pulled to start releasing air, the suction cup 33 disconnects from the adsorption.

[0072] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
